Hoping somebody much smarter than me can help me out here. These are some measurements of my 10 siht18's 4cf sealed. The no audyssey(no eq) measurement was taken a different day and at a different volume level but I think the other three I kept the mv the same for all. Those three are post audyssey with extra eq via minidsp. I went sealed because I had the space and budget to go multiple sealed and have never experienced single digit extension and I wanted to try it out. These are d4's powered by 3 inuke 6000's, 2 per channel at 4ohms for what I think is around 1100 watts per sub. I'm measuring with a omnimic v2 mic with calibration file which is supposed to measure down to 5 hz. The room is 14x15x9 with an open stairway to the upstairs. It looks like my output starts dropping at 12 hz and drops fast after 10. Is this the inuke's roll off? Other equipment is Onkyo txnr3007>Minidsp>inukes. I can bring it up some but the same general profile remains below 10hz. I had an idea and played around with the rew eq tab and simmed up some responses that get me flat to 5-6hz by pulling down everything above 12hz down to a couple db higher than the 6hz level. Then I thought I could just bring the whole response back up with the amp gains. Haven't tried it yet in reality only with the sim. Is this a horrible idea? I only know enough to be somewhat hazardous to my gear so I need some help. If I do this will I just be reducing my overall subwoofer headroom by whatever amount of db gain I add back? Even if all the eq cuts bring the entire response down by 10-12db then I add back 10-12db in amp gain. Would I be back at square one with the same headroom or will I lose it? Any other reasons this is a bad idea or is it a try it out and see what happens thing (which I will anyway)? Even with the huge boosts applied on the brown line I still wasn't clipping the amps with the incredible hulk end fight at -5 on the mv. I never watch higher than -12 in my room, its just too loud for me except for demos. Sorry for the long unorganized read of a post and I sure hope some smart folks made it all the way through, If theres anything I left out that will make it easier to help me with this please let me know.
Thank You in advance for any help at all,
